How are YODEL still in business?

Told me they attempted delivery. Flat out lie.

Said there was no safe space to leave the package despite the fact I have a concierge and a courtyard with no gate.

Went onto livechat and they were less than useless. First refused to do a thing. Second closed the chat before even responding. Third closed the chat after refusing to answer the question as to why no calling card was left.
